What is indicated by the term "acumen"?

The term "acumen" refers to a sharpness or keenness of judgment and insight, particularly in specific fields such as business, politics, or any area where decision-making is critical. When someone is described as having acumen, it implies that they possess a natural ability to understand and analyze complex situations quickly and effectively. This quality allows individuals to make informed decisions and recognize opportunities or potential problems.

In contrast, the other options suggest a deficiency in insight, such as a lack of understanding (lack of insight) or a passive state of mind (indifference). Self-doubt denotes a lack of confidence in one's judgment, which is the opposite of possessing acumen. Thus, the choice that reflects a positive quality of insight and judgment aligns perfectly with the definition of "acumen."
